X-Mirius? Siri-X?

The long-rumored merger between Sirius and XM is supposedly on. Moreover, at least one analyst thinks the move will win federal approval.

Don't know how anyone can make that leap, not with an activist Democratic congress yet to be heard from on the issue. For now, just the still unknown nut-and-bolts of how the two services would merge and which shows would migrate—does Stern go to Oprah, Oprah go to Stern?—are quite enough to ponder.
